LM22673QMRE-ADJ from Texas Instruments, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side NFET; the boot pin voltage is limited to VSW + 7 V per the absolute maximum ratings. |
| 2 | NC | unconnected | Not connected; the pin is not electrically connected inside the chip but functions as a thermal conductor. |
| 3 | IADJ | input | Current limit adjust input, where a resistor from this pin to GND sets the current limit threshold and the pin may be left floating for the internal default; the pin voltage is limited to -0.5 V to 7 V. |
| 4 | FB | input | Feedback input to the regulator; the FB pin voltage is limited to -0.5 V to 7 V. |
| 5 | SS | passive | Soft-start pin used to increase soft-start time; the SS pin voltage is limited to -0.5 V to 7 V. |
| 6 | GND | power_in | Ground input and system common for the regulator. |
| 7 | VIN | power_in | Supply input to the regulator, with a recommended VIN supply range of 4.5 V to 42 V and an absolute maximum of 43 V VIN to GND. |
| 8 | SW | output | Switching output of the regulator; the dc limit is -5 V to VIN relative to GND, with an extended -10 V limit for pulses up to 50 ns. |
